Ken, Paul, Chris, Walt.
We have 69 profiles in the database with many listings under Manufacturer.
California Sailplanes, DSK (Duster Sailplane Kits), the original designer Ben Jansson, are suggested alternatives.
Particularly as no hardware was manufactured for sale, I prefer to use the designers name throughout, thus,
Jansson BJ-1B Duster.
Any thoughts?
Malcolm.
